An anonymous researcher found evidence of memory corruption in the way Mozilla Firefox handles certain types of SVG comment DOM nodes. Additionally, Frederik Reiss discovered a heap-based buffer overflow in the conversion of a CSS cursor. Other issues with memory corruption were also fixed. Mozilla Firefox also contains less severe vulnerabilities involving JavaScript and Java.

Impact

An attacker could entice a user to view a specially crafted web page that will trigger one of the vulnerabilities, possibly leading to the execution of arbitrary code. It is also possible for an attacker to perform cross-site scripting attacks, leading to the exposure of sensitive information, like user credentials.
